NON-REFILLABLE BQTTLE.

Specification of Letters Patent.

Patented Aug. 31,- 1909.

Application filed February 23, 1909. Serial No. 479,573.

of New York, have invented certain new and useful Improvements inNon-Refillable Bot tles; and I do hereby declare the followingv to be afull, clear, and exact description of the invention, such as will enableJothers skilled in the art to which it appertainsto make and use thesame.

My invention relates to 'new anduseful improvements in non-refillablebottles and my object is to provide a device which will prevent thebottle from being refilled after eing once emptied.

A further object is to provide a device which may be introduced into thebottle at any time.

A further object is to provide means for permanently retaining thedevice within the bottle, and a still further object is to provide meansfor holding the device against rotation.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims. r

In the accompanying drawings forming part of this application, Figure 1is a central sectional view through the upper portion of a bottle neck,showing my improved nonrefilling device attached thereto. Fig. 2 is aperspective view of the non-refilling device removed from the bottle.Fig. 3 is a sectional view as seen on line 33, Fig. 1. Fig. 4 is asectional view as seen on ine 4-4, Fig. 1.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates the neckof a bottle, which may be constructed in the usual or any preferredmanner, within which neck is formed a circumferential groove 2, on whichis adapted to be seated a rib 3 formed around a stopper 4,

said stopper being preferably formed of metal and hollow.

The upper end of the stopper 4 is preferably semiglobular to form ahead5 and said head being of greater diameter than the stopper 4 to form ashoulder 6 which shoulder is adapted to rest on a gasket 7 positioned onthe upper end of the neckv 1,

thereby providing a non-leaking unionbe tween the stopper and the neckof the bottle. The stopper 4 is preferably flared from its intersectionwith the head 5 to its lower free end to fit the contour of the interiorof the neck of the bottle and in order to readily in- Etroduce thestopper into the neck of the bottle, the wall of said stopper isprovided with vertical slots 8 and horizontally disposed ';slots 9 atthe upper ends of the slots 8 and when the stopper is being introducedinto the 'bottle,.the lower end of the stopper is depressed and enteredinto the bottle. the stopper descends, the contracted wall thereof willgradually expand and cause the .rib 3 to enter the groove 2 and in orderto positively look the stopper within the neck Qof the bottle, a splitring 10 is introduced into the open end of the stopper and rests in thechannel 11 provided by extending the wall of the stopper to form the rib3 and as the ring is constructed of spring metal,

the tension thereof will cause the rib to snap into the, groove when thestopper has been properly seated in the neck of the bottle.

The head 5 is provided with a valve 12,

valve having a semi-globular base 13, which is preferably formed ofrubber, cork or like .material and is held in engagement with the valvein any preferred manner, as by means of a rivet 14.

The head 5 is provided on diametrically opposite sides with inwardlydirected projections or studs 15, which are adapted to engage the edgesof the valve 12 when the bottle is tilted to dischargethe contents ofthe bottle, and by always turning the bottle until the studs arehorizontally disposed, they form a pivot for the valve and permit thebottom portion thereof to swing outwardly and form a clear passage forthe contents of the bottle, although it will be understood that thevalve is of less diameter than the diameter of the interior of the headto form a space therearound through which the contents of the bottle maypass should the valve not be tilted. The apex of the head 5 is providedwith narrow slits 16, through which the contents of the bottle may bedischarged, said slits being so arranged and of such size that an objectcould not be introduced into the head and the valve lifted from itsseated position and the valve is normally held in its seated position bymeans of a spring 17, the upper end of which rests against the upperportion of the head 5, while the opposite end thereof rests on the valvel2, the tension of i said spring being such, however, as to permit thevalve to leave its seat when the bottle is tilted and the weight of thecontents of the bottle directed against the valve.

The stopper 4 is held. against rotating movement within the neck'l' byproviding seats 18 at diametrically opposite points on the interior wallof the neck, in which are adapted tobeseated teats 19 formed by striking outportions of the wall of the stopper 4,

seats 18 simultaneously with the entrance of y it will likewise be seenthat it will be impos sible to refill the bottle after the contentsthereof has been emptied, as the tension of the spring will hold thevalve' firmly seated as long as there is no weight pressing againstthevalve from the interior ofithe b'ottle.

What I claim is:

l. A device of the character described, comprising a tubular stopperadapted for insertion into a bottle neck, having a semiglobular headhaving its base offset from the stopper proper, said head being providedwith discharge openings in its rounded surface and a valve adapted toseat upon shoulders formed by the offset between said head and the bodyof the stopper, said valve having a depending semi-globular extensionupon its under side adapted to be received Within the body portion ofsaid stopper, and resilient means for the automatic retention of saidvalve seated.

or 2. A device of the character described,

comprising a tubular stopper adapted for insertion'within the bottleneck and having its outer end formed with an offset semiglobular head,said head having upon its rounded surface inwardly extending teats,

said head also having discharge 'openings through its central portion,said stopper having its body portion flared inwardly and provided withcircumferential ribs for engagement with corresponding recesses in thebottle neck, said stopper having longitudinal slots therein with theirupper ends terminating intrans'verse slots, a split spring ringreceivedby the depression formed by one of said ribs, a valve seatedupon the shoulder formed by the offset head portion of said stopper, andresilient means for the retention of said valve seated.

3. A device of the character described,

. comprising a tubular stopper having an offset semi-globular head, saidhead havin inwardly extending teats, and also provided with dischargeopenings in its central portion, said stopper having its body portionflared inwardly and provided with annular ribs adapted to engage likerecesses in the bottle neck, said stopper having longitudinal slotstherein terminatin at their upper ends in transverse slots, a split ringseated in the depression formed by one of said ribs, a

valve adapted to be seated upon a shoulder formed by offsetting saidhead of said stop per, said'valve having depending from its lowerside asemi-globular portion fitting within the body of said stopper and aresilient means for the retention of said valve seated.

two subscribing witnesses.
